To all whom it may concern:

Be it known that I, WILLIAM M. Hoi-inne, n citizen of the United States,residing ut Allegheny city, in the county of Allegheny und Stute ofPennsylvania, have invented certain new und useful In'iprovel'ueuts inWall-Plugs; und I do dechire the following; to be a full, clear, undexact description of the invention, such as will enable others skilledinthe art to which it appertains to make and use the saine, referencebeing had to the accom unying drawings, and to the figures of re Aercncemarked thereon, which form a part of this specification.

'Ihe object of this invention is to rovide a chen compact and durable waI plu that wi l securely hold the material desire to fasten against thewall und that can be readily applied where desired.

y invention relates to improvements in plugs for walls Where heretoforeblocks of wood und other plu s were used.

Itis designed to e placed between bricks either when erecting, orafterdhe walls are built, by removing material to make room between thebricks or making an opening in sog cement walls [urge4 enough to receivethe plu then when fastening the material to sai walls the nail is drivenbetween und through making a positive hold,

It consists of u piece of lnetulperforoted or notched and formed orcorrugated, euch side of seid holes or notches, and then bent closetogether forming u clump with extended lips at the open end us shown undhereafter more fully described. To enable others skilled in the nrt. towhich my invention in'ipertnins to construct und use the saine, I willnow describe it more fully, reference being hud to the accomplinying'draining forming por( ol this specification, in which Figure l is u persmotive. view showing the wall plugr sensed between tho bricks in u wull,ready for use. Fig. lis o vertical view showing the wall plugI in pincewith the. instel-inl nuilod to the wnll hy nie-uns ot' u nuil passing.rthrough suid nniteriul und extending through the closed notches of lheplug Fig. 3W-

u sertionul rien' of the plug,r showin;r ihr unil driven-in pince, undthe uniunvr el l'iolding-t`he nuil both, by nienns of the rorrogutionsund the sharp edges oi' Closell notrhef.

In Fig. 2 the plug is shown us used by.

driving u unil through the material Suid nail passing between vthecorrngutions und out through the notched portion thereby not only havingthe benefit of the ressure of the corrugutions, but also the sinrp edgesof the notches.

Where it becomes necessary to have the material to he fastened to thewall in u true line, and the surface ot wnll is irregular or not in utrue line, two or more of these plugs cnn be pluced one in the other, orwhat is known ns telescopios' together until the desired trueI line isacquired. This feature of lelesropingr is also of considerable advantagein fillingr lui-ge or irregular openings as in the ordinary rough stonewull, und to readily contorni the flanges oi the plug to n straightliiul in such wulls.

In Fig. 3 the effect of the nuil or other de.- vice for fus-toning isshown. The suid device forces the col'rugutions outwurdly ugninst thewoll, or substancebetween which the plug is plan-rd, und also pus-sesthrough the notched end, the` shnrp edges o'l which impinge un'ninsi theside of nul looking n secure hold. This fonture is very essential in theuse oi devices of this kind.

In addition to the advantages heretofore enumerated niy improved plughns the furv ther ndvnnlugr of being very cheap und eennoluirnl tomanufacture, us hy reason of the nuiicrinl being of one piece, und eutwithout u'nsle of uiuteriul. Another udvuntngc is that this plug eun beunido in nny length which is of great udvnntuge for cement or brickIloors or ns joisls vFor [mrtitions to hohl lnihingg or wuinscoting.

l rhiirn :is now und desire to secure by Letters Intenl l. woll plugconsisting of n single piece of corrugated uuderiulforming :t seriosofridges und depressions und h-nving n. rentrnl irons-verse line ofperforulions pnrullel to seid-ridges. the .sold stri@ or picco beingfolded together on :i line through the perforations, thereby formin aclamp havin its ridges and depressions a ternating witht ose on theopposite side and forming an irregular restricted space between thewalls of the clamp. g

2. A wall plug consistin of a singlepiecc of corrugated material avin acentral transverse line of perforations, t e said iece being foldedtogether on a line throug the perforations, thereby forming a clarlnpwith gripng edges at folded per orations as descri ed.

3. A wall plug as described consisting of a single piece of stampedmaterial .folde together, and having its foldedsedge notched out, therebforming a clamp with gripping edges. at fo ded edge through notchin s.

4. A wall plug consisting of a. sing e piece of material corrugated soas to .form a series of ridges and depressions, its ends bent or flaredoutwardly and then folded together, and folded edge notched to form agrip as described.
